Objective To investigate the value of MSCT for preoperative clinical staging diagnosis and recurrence pre-diction in patients with oesophageal cancer.Methods Retrospectively selected 108 cases of esophageal cancer patients,all of whom underwent MSCT before surgery,and analyzed the diagnostic value of MSCT on T and N staging and the predictive value of recurrence in patients with esophageal cancer,using surgical pathology examination as the gold standard.Results MSCT diag-nosed esophageal cancer T-stage T1 in 7 cases,T2 in 21 cases,T3 in 47 cases,and T4 in 23 cases,and the diagnostic accuracy was 90.7％,which was in good agreement with pathological examination result(Kappa=0.88),and the difference was not statis-tically significant(x2=0.124,P=0.988);The diagnostic accuracy of MSCT was 91.7％,which was in good agreement with pathological examination(Kappa=0.82),and the difference was not statistically significant(x2=0.003,P=0.958);Gender,age,T-stage,chemotherapy and GTV-L were not correlated with recurrence,while among patients with recurrence,N1 stage,GTV-D≥ 3.5 cm,GTV-V≥23.8 cm3 and GTV-V/L ≥ 3.5 cm were higher among patients with recurrence(all P＜0.05);Logistic re-gression analysis showed that GTV-D,GTV-V and N stage were all independent influencing factors for recurrence in patients with esophageal cancer(P＜0.05).Conclusion MSCT has a very high clinical value for preoperative staging and recurrence risk pre-diction of esophageal cancer,and GTV-D,GTV-V and lymph node metastasis were found to be independent risk factors for recur-rence of esophageal cancer,so MSCT can be one of the main examination modalities for preoperative evaluation of esophageal cancer.
